Recent media reports in some parts of the country have
highlighted concerns related to elevated levels of lead in the
Golden State Water would like to assure customers that we monitor
and test regularly to ensure the water we deliver to customers
meets all state and federal drinking water standards, including
those for lead and copper as found in the Lead and
The US Environmental Protection Agency (USEPA) and State Water
Resources Control Board regulate testing for lead and copper to
protect public health. For systems like Golden State Water that
have a good history of meeting the Lead and Copper Rule
requirements, a survey is conducted every three years to ensure
lead levels remain below the drinking water Action Level of 15
ppb (parts per billion). If a water system exceeds this
Action Level, it can trigger other requirements which include
more frequent water quality testing, source monitoring and
possibly corrosion control treatment.
These tests are required to be taken at certain customer homes
that would be considered the highest risk for lead exposure,
including single-family structures that contain copper pipes with
lead solder installed after 1982.
Golden State Water makes water quality information available via
Confidence Reports (CCR), and any levels of lead
detected during tests that exceed the detection limit for
reporting would be published in your community’s report. (Please
note: Golden State Water’s systems have all met the standards for
lead testing, thus there is no mention of lead testing results in
Water quality test results are directly submitted by the State
certified laboratory to the State of California’s Division of
Drinking Water (DDW) and recorded on the State’s website for full

As your water provider, we continually invest in water
infrastructure, treatment and testing and take great pride in
providing you with safe, reliable water.

Facts About Lead In Drinking Water
Lead is a naturally occurring element that can cause health
concerns when ingested by humans or animals.
Lead in drinking water is most commonly the result of
corrosive water breaking down service lines and home plumbing
infrastructure constructed with lead.
Structures built before 1986 are more likely to have lead
pipes, fixtures and solder. Some structures built after 1986 may
also be at risk, as even “lead-free” plumbing may contain up to 8
Beginning January 2014, changes to the Safe Drinking Water
Act further reduced the maximum allowable lead content of pipes,
pipe fittings, plumbing fittings, and fixtures to 0.25 percent.
The most common problem is with brass or chrome-plated brass
faucets and fixtures with lead solder, from which significant
amounts of lead can enter into the water, especially hot water.
To address corrosion of lead and copper into drinking water,
EPA issued the Lead and Copper Rule (LCR) under the authority of
the Safe Drinking Water Act. The LCR requires corrosion control
treatment to prevent lead and copper from contaminating drinking
water. Corrosion control treatment means systems must make
drinking water less corrosive to the materials it comes into
contact with on its way to consumers’ taps.
Lead can affect almost every organ and system in your body.
Children six years old and younger are most susceptible to the
effects of lead.
Lead is particularly dangerous to children because their
growing bodies absorb more lead than adults do and their brains
and nervous systems are more sensitive to the damaging effects of
lead. Even low levels of lead in the blood of children can result
in: Behavior and learning problems; Lower IQ and Hyperactivity;
Slowed growth; Hearing Problems; Anemia; In rare cases, ingestion
of lead can cause seizures, coma and even death.
Lead can accumulate in our bodies over time, where it is
stored in bones along with calcium. During pregnancy, lead is
released from bones as maternal calcium and is used to help form
the bones of the fetus. This is particularly true if a woman does
not have enough dietary calcium. Lead can also cross the
placental barrier exposing the fetus the lead. This can
result in serious effects to the mother and her developing fetus,
including: Reduced growth of the fetus; Premature birth.
Lead is also harmful to other adults. Adults exposed to lead
can suffer from: Cardiovascular effects, increased blood pressure
and incidence of hypertension; Decreased kidney function;
Reproductive problems (in both men and women).
